On Thursday, August 4, 2011, more than 360 guests gathered at the GUESS flagship store on Michigan Avenue to kick off Chicago’s most celebrated music festival, Lollapalooza, for a special event with Nylon magazine.

To give guests a sneak peek into the upcoming weekend, GUESS hosted three up-and-coming performers who treated partygoers to exclusive performances: L1GHT, Dale Earnhardt Jr. and The Vaccines.

In addition to listening to the sets, attendees were encouraged to shop GUESS merchandise, take photos at the Nylon photo booth, enjoy appetizers from the Entertaining Company and sip summer drinks courtesy of Van Gogh Vodka and Dirty Blonde cocktails.
